OpenSSL SSL/TLS Handshake Processing Weak Encryption Usage Information Disclosure Vulnerability

 
Threat Type:CWE-310: Cryptographic Issues
IntelliShield ID:34548
Version:10
First Published:2014 June 05 21:05 GMT
Last Published:2014 July 14 13:02 GMT
Port: Not available
CVE:CVE-2014-0224
BugTraq ID:67899
Urgency:Unlikely Use
Credibility:Confirmed
Severity:Mild Damage
CVSS Base:5.8 CVSS Calculator
CVSS Version 2.0
CVSS Temporal:4.5
 
Version Summary:HP has released additional security bulletins and software updates to address the OpenSSL SSL/TLS handshake processing weak encryption usage information disclosure vulnerability.
 
 
Description
A vulnerability in the Secure Socket Layer (SSL)/Transport Layer Security (TLS) functionality in OpenSSL could allow an unauthenticated, remote attacker to conduct man-in-the-middle attacks.

The vulnerability is due to weak cryptographic keys that could be determined by an attacker. An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted handshake packet to a targeted system. If successful, the attacker could perform a man-in-the-middle attack against the system, allowing the attacker to modify or decrypt traffic between the targeted system and another system running the vulnerable application.

Proof-of-concept exploit code is publicly available.

OpenSSL has confirmed the vulnerability and released software updates.
 
Warning Indicators
The following OpenSSL versions are affected:
  • OpenSSL versions prior to 0.9.8za
  • OpenSSL versions prior to 1.0.0m
  • OpenSSL versions prior to 1.0.1h
 
IntelliShield Analysis
A successful exploit could allow the attacker to intercept traffic that is traveling from a TLS client to a TLS server or vice versa; however, both systems must be using an affected version of OpenSSL. In addition, attackers may also require a privileged position in the network environment to capture network traffic, increasing the difficulty of leveraging information gained from exploits against the vulnerability.

Impact
An unauthenticated, remote attacker could exploit this vulnerability to perform a man-in-the-middle attack between an affected OpenSSL SSL/TLS client and server systems. A successful exploit could be used to conduct further attacks.
 
Technical Information
The vulnerability is due to weak cryptographic keys that could be determined by an attacker.

An unauthenticated, remote attacker could exploit this vulnerability by sending a crafted handshake packet to a targeted system. If successful, the attacker could perform a man-in-the-middle attack against the system, allowing the attacker to modify or decrypt traffic between the targeted system and another system running the vulnerable application.
